IMPROVEMENT IN BOILERS.

TO ALL WHOM I'l MAY CONCERN:

Beit known thatwe, CHAUNGEY O. GREENE and ROBERT HAM, cachot the city ofTroy, in the county of Rensselaer, and State of New York, have jointlyinvented certain new and useful Improvements in Water- Reservoir Stovesand Ranges; and we do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had tothe annexed drawings, and the letters ofreference marked thereon, and makingpa 'part of Vthis specification, inwhich- Figure l is a perspective view, and showing the water-reservoiras in its hack or realposition on the stove-top.

Figure 2 is a perspective view, and showing the water-reservoir asturned around to its front position, and over the pot-holes on thestove-top.

Figure 3 is a view of the bottom side of the water-reservoir, showing africtiondlange thereon` Figure 4 is atop or plan view of awater-reservoir stove, and showing diiierent positions that thewaterreservoirrmay be shifted into, and made to rest in at diEerenttimes on the stove-top; and

Figure 5 is a vertical longitudinal sectional view of tig. 4.

The same letters refer to like parts in each of the s aid figures.

The object of our said invention is to produce a water-reservoir stoveor range, whereof the water-reservoir may be conveniently and readilychanged or shifted around from the cooler to the hotter places, andreversed upon the stove or range-top, and be so operated or moved tothat end, without necessity -for dctachingor lifting said reservoir fromthe stove or range-top, when'so changing its places thereon, for thepurpose ofregulating the temperature of water within said reservoir toany heat desired, from warm-to that of boiling heat; andthe nature ordistinguishing features ofthe said invention consist in thewater-reservoir of the stove or range being so pivoted or hingedthereto, that the said water-reservoir is' made capable of,and it may,without lifting it or detaching it from the stove or range-top, beturned, revolved, or shifted around, or part way around, horizontally,or nearly so, about its pivot-centre thereon, and thereby made to restupon or over various differentlyheated parts of the stove or range-top,atdiiierent tintes, substantially in manner asgher'einafter fullydescribed and sho'wn,'so that the temperature of water within saidreservoir may thereby be regulated from a warm to a boiling heat, aswanted for various culinarind other uses.

The said invention also consists in the construction and combinationoftcertain mechanical devices, substantially as hereinafter fullydescribed and shown, with stove or range-tops and theirwater-reservoirs, whereby the water-reservoir thereof is 'securedthereto in such manner as to be easily shifted or moved on and-aboutits.

pivot-centre, from one position or place to another-position or place onsaid range or stove-top, for the purpose aforesaid, l l

To enable others skilled in the art to make anduse our said inventionand improvements,- We will now pro oecd to fully describe itsconstruction and operation, to wit: n l l In iig. 1, of the annexeddrawings, B shows a shifting or turning hot-water eservoirpprovided withhinged lids or covers, and mounted' upon and hinged or pivoted to thetop-plate A of a cooking-stove or range, Ofcom struction, in manner, andby devices substantially as follows: In the front side of thewater-reservoir B, a recess, Q, extending through or from top to bottornis made or cast therein, and the bottom part or edge ofthis recess isextended at right angles, or nearly so, to said recess, and inward, 'soas to form a flange or shoulder, e, con; centric with said recess, andfastened by rivets, or otherwise secured to and over, so as to encloseand form the front partei' wall of said recess, is un arched plate, D,which has formed on and at its bottom 'inside'face, a section offlange-or shoulder, which makes even jointwith the flange e aforesaid,andserves to make' complete therewith an annularorcontinuous'ring-Hangs, e, atthe bottom of said recess-G, and saidflange has made in its back Yor rear part, a notch, lv. Thelconstruction and arrangement oi the aforesaid devices is fully shown ings. 3, 4, and 5, of annexed drawings. There is formed on or attached tothe front of the pipe-collar h.of the exit-passage C, a holding-lug, a,projecting laterally orv horizontally therefrom, and arrangedsuiiiciently up fromV the surface of stove-tcp A to allow the aforesaidring-Hangs 4e to move freely under said lug a, when adjusted incombination there Aith and thereunder. i

Formed on or attached to the under side or. bottom of saidwater-reservoir B, is an anti-friction flange or flanges or ribs, g, orsuitable equivalent devices therefor, such as friction-wheels orrollers; or the said :intifriction devices may be attached to the stoveor range-top A, instead, and effect their purpose, but we prefer them onthe-bottom of the reservoir, substantially as shown in iig. 3, andarranged thereon concentricnlly, as

shown. v

This Water-reservoir B, as thus constructed, is now mounted uponthe-stove or'range-top A, as prepared for it, and secured thereon, tooperate in combina-tion" therewith, by placing it thereon, with its rearor back side square to the front of the stove or range-top, in manner asshown'in fig. 2 of annexed drawings, atwhich position the lug a andthenotch b aforesaid are made to coincide, so that the said notch passesthe said ringlange into the proper position for it to more under the luga., when'turning'the said reservoir about horizontally in right or inleft directions, torshift or change the saine about its thus-.formedpivotcentre, into different places on the stove-top, within its circleof movement thereon. When the said reservoir is shifted or turned intothe position to cover partly the pot orv boiler-holes E E, as shown .infig. 2, the lids or covers thereof, and centrepiece F, may he removed,if desired, and a removable coveror hood, I, placed thereon, and joiningthe reservoir i side, andalso so as to enclose under it a part ofthereservoirs side, and so increaseits direct heating-surface.

The said iig. 2 shows fully only Abut a part of said' cover I, the restbeing shown by dotted lincs,rt,o thereby better show the openingjclosedby said covering-plate. The pipe C, for the exit of the gases of'eo1nbust`ion,is placed in the usual manner over thepipe-collar, and isor muy be held up'thereon by the' lug a, or on saidlug and ashoulder-support, the collar bei'ng'made somewhat higher than iscustomary, so as to serve also asa pivotcentreas aforesaid, for `thewater-reservoir B, which shifts or turns theeabout, without support ofor contact with said exit-pipe.

This new improved water-reservoir stove or range is managed or operated.to effect its purposo'of heating water therein to any intermediatetemperature, from warm up to a b'oiling heat, inclusive, in manner asfollows: f

For warm water only, change or shift the-ivaterreservoir B, by turningit about its pivot-centre, intol its least hot place, as in rear f theexit-pipe C, and on the back end vbf the stove or range-top, in manneras shown in iig. 1. When water still warmer is wanted, but not of aboiling heat, again shift the said reservoir, by turning it intoposition lengthwise with the stove-top or side, in manner as shown bythe black linesin figs. 4 and 5.; and when boiling-hot-water iswanted,'the said reservoir is then to be shifted or turned on and overthe hottest place for it on the said top, and in position as shown iniig. 2, in which position the water therein, is made boiling hot. Theblue and red lines in said g'. 4 show other and some of the intermediatepositions on the stove or rangetop, into which the said water-reservoirB may be shifted or changed, byturning it about its pivot-centre, l

in manner as aforesaid.

i The said water-reservoir, inits shifting or changing movementsY fromone position to another on and about the stove or range-top, moves atall times easily, and with 'little' friction thereon, and on and aboutits pivot; centre, because the aforesaid friction-iange or flanges onthe reservoir-bottom presentbutsmall 'surface of contactwith and on thestove or range-top, and witbthe leverage obtained by applying the movingforce atlthe end orends of the waterreservoirhand when the stoveorrange-top is occasionally blacked over with plumbngo of black lead," soovercomes and lcssens friction, that the said awater-reservoir or tankis moved easily thereabout, when brimful of water.

What we claim as our invention, and desire to secure by yLetters Patent,is-

1. In combination with a cooking-'stove or range, we claim awater-reservoir or boiler, B, when hinged or pivotedto or upon saidstoy-cor rangetop, in manner such that the said water-reservoir orboiler fmay be turned, revo1ved,'or shifted thereon about itspivot-centre, andthereby be made to rest upon or over thedifferentlyheated parts of said stove or range-top, to thereby increaseor decrease, or regulate the temperature of water within said reservoiror boiler, substantially in manner as hereinbefore described' and shownfor the aforesaid purpose.
